SPECIFICATION forming part of Letters Patent No. 266,878, dated October SLQSSZ Application filed August 17, 1882. (No specimens.)

.To all whom it may concern:

Be it known that I, ANTONIO PELLETIER, a citizen of the United States, residing atVVashington, in the District of Columbia, have invented certain newand useful Improvements in Compounds for Artificial Stone; and I'do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make'au'd use the same.

This invention relates to certain improvements in compounds or cements for the construction of artificial stone and other like purposes; and I do hereby declare that the following is a full, clear, and exact description thereof. I

To enable others skilled in the art to which my invention appertains to make and use the same, I will proceed to describe it.

In preparing my improved material I first make a suitable cement from material which, upon heating, gives rise to its formationnamely sul mate of alumina or other cheap salts of alumina or aluminous materials--such as felds ar ranite furnace-sla s &c. toge er Wl 1mm or 0 er as-house lthenmixt eprepared cemen, Wl s1 iclous'sand and oxide of iron or other metallic salt, with saLmW c lorideof'aiiysuitalile minera or e sesuimofiuesr 'irafi'raany ssiaitis proportm 3mm to form a mass of suitable The proportions may be varied as occasion or the nature of the work requires but I have found the following to answer well for general purposes, viz: cmen composed of sulphate of alumina or 0 er 0 cap salts of alumina or aluminous materials-such as feldspar, granitc, furnaces'lags, Ste-together with oystershellsor other gas-house lime, (dolomite limestone,) one part; silicious sand two parts;

ture of artificial stone. The sal-ammoniac or army as specified.

othegehlorides and the ses'lguichioride of Iron,- in about'equal parts or at or em a c proportions, are combined with water in about the,

a ove described-via, the cement prepared as described, sand, and metallicpgide-Me thoroughly mixed by any suitable means and a sufficient quantity of the last-mentionedehloride r or compound chloride solution added to form a highly-plastic mass,which may be molded into blocks of various sizes and shapes, or which may be applied as a coatin for wood,

alls of various descriptions, to roofs, and to innumerable other purposes where a durable 6 5 and hard surface 'or body is required. The Elastic mass will dry rapidly and become as ard as arock, and will render articles to which it is applied not only thoroughly water-proof, but fire-proof as well.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1sa v 1. The chloride or compound cl lggide solution, adaptedtb'be comhined'w'itlia hydraulic cement, sand, and a metallic oxidembstah 2. The compound consisting of the cement prepared as described, silicious sand, oxide of iron or other metallic oxide with sal-ammoniac 8c and corresponding ses uichloride and water combined, substantially sRcTfieHI 3. The compound solution for mixing, employed to render' plastic the material for the formation of artificial stone, consistingof chloride of ammonia or other suitable chloride and corresponding sesquichloride, substantially as specified.

In testimony whereof I afiix in presence of two witnesses.
